    Test data selection for software represented as Boolean formulae has not received much attention until the last decade. Most of the approaches are expression driven because generation of test cases is based on the Boolean formulae being tested. The paper discusses test data generation using a fault based approach in the sense that generation of test cases is based on particular types of faults occ... View full abstract»

  • An optimization of disjunctive queries: union-pushdown

    Most previous works on query optimization techniques deal with conjunctive queries only because the queries with disjunctive predicates are complex to optimize. Hence, for disjunctive queries, query optimizers based on these techniques generate plans using rather simple methods such as CNF- and DNF-based optimization. However, the plans generated by these methods perform extremely poorly for certa... View full abstract»

    The Internet File System (IFS) extends the scope of file systems from LANs to the Internet, encouraging collaboration and information dissemination on a much broader scale. In addition, Internet resources (e.g. Web pages, Gopher Information, and Network News) become files in IFS, allowing file system APIs and existing tools and commands to be used to manipulate Internet resources just like convent...

    Many large software systems are tightly integrated with their physical environments and must be adapted when their environment changes. Typically, software development methodologies do not place a great emphasis on modeling the system's environment, and hence environmental changes may lead to significant and complicated changes in the software. We argue that (1) the modeling of the environment sho... View full abstract»

  • Efficient methods for kr→r and r→kr array redistribution

    Publication Year: 1997, Page(s):82 - 87
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (476 KB)

    Array redistribution is usually required to enhance algorithm performance in many parallel programs on distributed memory multicomputers. Since it is performed at run-time, there is performance tradeoff between the efficiency of new data decomposition for a subsequent phase of an algorithm and the cost of redistributing data among processors. We present efficient algorithms for array redistributio... View full abstract»

    The concept of transactions is not only indispensable in database applications, but also useful in building robust software for mission critical applications. The paper presents an implementation of the Object Transaction Service (OTS) based on CORBA 2.0 specification. Transactional applications developed with the support of our OTS implementation are able to assure the ACID properties even in the... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (512 KB)

    One major problem in inter class integration testing of object oriented software is to determine the order in which classes are tested. This test order, referred to as inter class test order, is important since it affects the order in which classes are developed, the use of test stubs and drivers for classes, and the preparation of test cases. The paper first proposes a number of desirable propert... View full abstract»

    We report an effort to lift the conceptual level of Java programming for communications in control systems to the level of CODARTS interfaces. Having implemented every component of the communication interfaces defined by CODARTS, we have constructed a Java class library that facilitates a direct mapping from CODARTS design diagram to Java program components. This will not only simplify the program... View full abstract»

    Software integration is an important and useful approach to software reuse. Most of software integration approaches use data-integration paradigm, i.e., common data format and (or) source code are required for integration. The author proposes a functional integration approach which integrates software by functionalities. No common data format or source codes of the integrated software is required ...

    Software has made more progress during the last few years than any years before that. New technology is coming every day and it is impossible for every one to catch up with it. Two technologies and their impacts on software development are presented: software reusability, which can significantly improve software productivity; and Internet computing, which provides a new testbed for software applic...

    Existing temporal databases focus on the management of data history. However, it may be required to know how users, procedures and policies affect the data value changes in decision support system and database debugging or maintaining systems. If so, the object model needs to incorporate the behavioral modeling of data objects. We propose a model using finite state machines, method signatures and ... View full abstract»

  • Application of data-centered approach to Year 2000 problem

    The data-centered approach uses variable classifications, dependence analysis, generalised program slicing and ripple effect analysis. In the Year 2000 problem, this approach can be useful. Variable classification is used to identify all input and output variables, and once the initial set of variables that are Year 2000 related is identified, dependence analysis can be used to identify all the va...

    The SCR method models a system using a set of variables and state machines whose behaviour is described by tabular notations. This paper proposes an interleaving semantics for SCR specifications in terms of timed transition systems. The semantics is given by identifying each of the components of a timed transition system from a given SCR specification. The concurrent behaviour of a SCR specificati... View full abstract»
